I am really impressed with this update

The touch behavior is MUCH improved. Accuracy is great and the screen doesn't freak out and jump all over the place anymore when trying to scroll.
The keyboard is also more accurate and key presses register more quickly. Having a functional autocomplete dictionary is also a huge plus!
The send screen to e-ink feature is nice, as well as, the updated version of ES File Explorer (v1.4.0). For those complaining about the camera quality, you can change the resolution. The default is vga, but can go up to 3M.
